Within its fleet of machinery and equipment, TBT Piling (Sabah) Sdn Bhd maintains hydraulic vibratory hammer mechanisms for use with both excavator and crawler crane, for the installation / withdrawal of steel sheet piles in accordance with ‘BS EN 12063:1999 Execution of special geotechnical work – Sheet-pile walls’.
Through modern hydraulic attachments, vibratory hammers drive or extract steel sheet piles by applying rapidly alternating vertical forces to the clamped piles. They offer the advantages of high rates of penetration, reduced ground vibration and noise levels, and the possibility of extraction/correction of misplacement errors, which can translate to significant economic savings and improved project environmental issues.
The currently available vibratory systems are capable of installation of steel sheet piles of various lengths, to form a continuous soil retaining structure of lapped or interlocking individual sheet piles, with the assistance of guide-frames (if required).
Services offered include installation / extraction of temporary/permanent sheet pile walls for earth retaining or cofferdam structures in land or near-shore marine environments. The equipment may also be utilised for the insertion/extraction of temporary/permanent steel casings for bored pile construction, and installation of steel pipe piles.
For a more detailed description of the methods and procedures involved in installation of steel sheet piling, reference should be made to the TBT Piling (Sabah) Sdn Bhd standard method statement.
